Definitions

  • the invention relates to a valve for regulating a fluid flow, in particular an air flow.
  • the invention relates in particular to a valve for regulating a flow of fluid arranged in an engine environment of an aircraft.
  • the invention also relates to an air conditioning system comprising such a valve and also relates to a ventilation system comprising such a valve.
  • An air conditioning system for an aircraft cabin generally comprises a device for withdrawing compressed air from at least one compressor of an aircraft propulsion engine and an air cycle turbomachine comprising at least minus a compressor and a turbine, the compressor being supplied with air by the compressed air sampling device after passage through a flow or pressure regulation valve, and the turbine comprising an air outlet supplying the cabin with temperature and controlled flow.
  • the air conditioning system also includes various heat exchangers, control valves and a water extraction loop.
  • An air regulation valve is intended to allow the control of the air flow circulating in the air circulation pipe equipped with this regulation valve.
  • Such a control valve can be arranged in the engine environment, that is to say, in the engine nacelle or in the immediate vicinity of the engine, on the air sampling pipes.
  • Such a control valve is also used in the air ventilation systems of aircraft engines which are housed in the engine nacelle.
  • control valves in an engine environment requires to associate them with valve actuators which can withstand the high temperatures prevailing in this engine environment.
  • a valve controlled by a hydraulic actuator whose control fluid is the fuel.
  • This hydraulic fuel actuator controls the opening and closing of the valve.
  • the actuator is for example provided with a displacement sensor, such as a displacement sensor known by the acronym LVDT for “ Linear Variable Differential Transformer ”.
  • This LVDT sensor detects the passage of the control fluid, in this case the fuel, and conditions the opening or closing of the valve.
  • the actuation of the valve is therefore obtained by the fuel pressure on the hydraulic actuator which causes the displacement of the valve closure member, such as a butterfly.
  • the hydraulic actuator When the valve is housed in the engine environment, the hydraulic actuator, also housed in the engine environment, is subjected to high temperatures which can reach nearly 500 ° C. during the flight of the aircraft.
  • the hydraulic actuator is cooled by the fuel that controls the actuator.
  • the use of fuel as a muscle fluid to drive the hydraulic actuator can have drawbacks, particularly in an engine environment. Indeed, the fuel circuit must be sized so that the fuel pressure controls the hydraulic actuator. In addition, the use of a fuel circuit to drive the actuators increases the consumption of the fuel pumping system and can also lead to risks of fuel leakage. Also, the use of a fuel actuator generates integration constraints which can prove to be complex and / or costly to take into account.
  • the assembly formed by the valve and its hydraulic actuator has a bulk and a significant weight which can impact the energy performance of the aircraft.
  • the inventors therefore sought to develop a new solution for controlling the fluid, and in particular air, control valves, adapted to engine environments.
  • the invention aims to provide a valve for regulating a fluid flow, in particular an air flow, which can be fitted within an engine environment of an aircraft which overcomes at least some of the drawbacks of known solutions. .

  • a valve according to the invention is characterized in that said electric actuator is arranged at least partially in said fluid circulation channel so as to allow its cooling by said fluid circulating between the fluid inlet and the fluid outlet of said body of valve and in that said closure member comprises two concentric elements conjugate: a fixed element relative to said valve body and a rotary element relative to said fixed element, called plug, controlled by said electric actuator.
  • a valve according to the invention therefore has the particularity of using an electrical actuator and of integrating this actuator at least partially into said fluid circulation channel of the valve body so that this electrical actuator can be cooled by the flow of fluid circulating in the valve circulation channel.
  • This electric actuator can also be associated with a reduction gear to drive the shutter member. Where appropriate, the reduction gear is also housed in said fluid circulation channel.
  • a valve according to the invention makes it possible both to regulate a flow of fluid (by actuation of the shutter member) and to cool the actuator of this shutter member (by the bias of the fluid flow circulating in the circulation channel in which the actuator is housed).
  • a valve according to the invention makes it possible to dispense with a dedicated ventilation for the electric actuator. This removal of dedicated ventilation thus makes it possible to remove an air intake dedicated to cooling the actuator and therefore to maximize the useful air flow in the system in which the valve is integrated.
  • a closure member which can have at least a first position, called the open position, allowing the circulation of a fluid from the inlet to the outlet of the body fluid valve, and at least a second position, said closed position, in which the closure member prevents, at least in part, the circulation of a fluid in said valve body.
  • the fluid flow rate In the position, called the open position, the fluid flow rate is maximum through the shutter member. In the position, called the closed position, the flow of fluid is minimal through the closure member.
  • the closure member prevents any circulation of fluid in the closed position.
  • the shutter member extends across the circulation channel to block the passage of fluid in the closed position. In other words, the minimum fluid flow corresponds to a zero flow.
  • the shutter member blocks only part of the flow in the closed position. This variant allows for example to maintain a fluid leak when the shutter member is in the closed position.
  • the shutter member comprises two concentric elements combined: a fixed element relative to said valve body and a rotary element relative to said fixed element, called a plug.
  • the electric actuator allows the displacement of the shutter member and therefore the regulation of the fluid flow.
  • This actuator can itself be controlled by a control unit configured to impose the position of the closure member in the fluid circulation channel.
  • the electric actuator drives in rotation, the plug, by means of a reduction gear, relative to the fixed element allowing the shutter member to have at least one open position allowing the passage of fluid and at least one closed position at least partially limiting the passage of fluid.
  • the rotary element is designated by the term bushel or by the term shirt.
  • the actuator controls the open and closed positions of the shutter member and the fluid flowing in the circulation channel cools said actuator.
  • the electric actuator therefore makes it possible to coordinate the two concentric elements combined to regulate the circulation of fluid.
  • the shutter member can also be controlled by the electric actuator to occupy at least one position, called the intermediate position, in which the fluid passage section is intermediate between the minimum passage section corresponding to the closed position and the maximum passage section corresponding to the open position of the valve.
  • valve according to the invention which integrates the electric actuator in the fluid circulation channel, has a reduced bulk.

  • This particular arrangement makes it possible to limit the vibrations of the assembly formed by the valve and the actuator.
  • the channel may for example be a channel with symmetry of revolution and the actuator is arranged on this axis of symmetry of revolution.
  • This specific arrangement also makes it possible to isolate the actuator electric motor environment by forming an air mattress between the electric actuator and the external motor environment, including when the circulation line is not supplied with air. This air mattress limits the thermal conduction between the electric actuator and the engine environment.
  • said electric actuator is arranged upstream of the shutter member.
  • said actuator is arranged upstream of the shutter member, so that the fluid can cool the actuator before passing through the shutter member when it is in the open position which allows the passage of fluid.
  • This variant also allows the actuator to be cooled even when the shutter member is in the closed position which limits the circulation of the fluid inlet towards the fluid outlet of the valve.
  • the closure member may comprise at least one orifice with a longitudinal axis configured to allow the formation of a fluid leakage through the closure member. This ensures cooling of the electric actuator, regardless of the arrangement of the actuator relative to the shutter member.
  • said plug of said shutter member defines a central duct which comprises a sealed transverse wall.
  • said sealed transverse wall extends perpendicular to the longitudinal direction so as to impede circulation in the longitudinal direction downstream of this wall and thus improve sealing.
  • the sealed transverse wall can be formed for example by the actuator and more particularly by the casing protecting the actuator, or any element closing off said central duct at one end in order to constrain the circulation of the fluid while ensuring sealing.

  • the conjugate concentric cylindrical elements have a circular base.
  • said shutter member therefore comprises two conjugate concentric cylindrical elements, one of which, said to be internal, has a first diameter, and the other, said to be external, has a second diameter larger than said first diameter of the internal cylindrical element.

  • the conjugate concentric elements include fluid passage openings in order to be able to regulate the flow of fluid circulating in the circulation channel.
  • the size and shape of the lights is such that for a defined angle of rotation of the plug, the passage of the fluid is completely closed or completely open. All intermediate positions allow regulation of fluid flow inside the fluid circulation line.
  • Comparing the respective lights of the fixed element and the plug makes it possible to free a radial passage section through which the fluid can circulate freely.
  • each concentric element comprises an odd number of fluid passage openings regularly distributed over its wall.
  • An odd number of fluid passage openings makes it possible to improve the distribution of the forces and to limit the opposing forces exerted by the fluid flow on the conjugate concentric elements, in particular when the concentric elements are cylindrical.
